The languages that we currently support on Kickstarter are: English, French, German, Japanese, and Spanish. If your project includes text or audio in a language outside of these, we do recommend that you include English translations or subtitles where possible.
As a creator, it’s important to build your project with your target audience in mind. If you anticipate your backers will be mostly Spanish-speaking, then you may want the main language on your project page to be Spanish. However, including an English translation as well will help your project have a wider appeal. Kickstarter is a global community, with more than 75% of backers on Kickstarter coming from English-speaking countries.
